2. Note

Please read these operating instructions before unpacking and putting the unit in operation. Follow the instructions precisely as described herein. The devices are only to be used, maintained and serviced by persons familiar with these operating instructions and in accordance with local regulations applying to Health & Safety and prevention of accidents. When used in machines, the measuring unit should be used only when the machines fulfil the EWG-machine guidelines.

3. Instrument Inspection

Instruments are inspected before shipping and sent out in perfect condition. Should damage to a device be visible, we recommend a thorough inspection of the delivery packaging. In case of damage, please inform your parcel service / forwarding agent immediately, since they are responsible for damages during transit. Scope of delivery: The standard delivery includes: • Device model: TWL • Operating Instructions

4. Regulation Use

The temperature sensors of series TWL are suitable for all applications where processes involving fluids, solid bodies or materials, or gases, require temperature recording and measurement. Our temperature sensors are suitable for use in the following industrial areas: chemicals, petrochemicals, water, feed, food, sanitary, etc. Any use of the Temperature Sensor, model: TWL, which exceeds the manufacturer’s specification may invalidate its warranty. Therefore, any resulting damage is not the responsibility of the manufacturer. The user assumes all risk for such usage.

TWL

page 4 DT0454

5. Operating Principle

Resistance thermometers work by using the continuous change of resistance of metals subject to temperature rising and decreasing. The most common resistance material used is platinum, as it is very stable and has very good repeatability. The temperature coefficient of platinum is positive, so its resistance increases as the temperature rises. This property is defined in the IEC751 standard, which defines measurements deviations categories A and B.

7. Use in hazardous Areas

7.1 Area of validity These security instructions apply to TWL Series temperature sensors and their accessories for use in explosion-proof atmospheres conform to CE certificate LOM 08ATEX2016 X 7.2 Guidelines The TWL Series temperature measuring instruments work according to the heat resistance measuring principle. This measuring principle acts to check and measure the temperature also in explosion-proof areas. TWL devices can be with a standard 4 to 20 mA signal transmitter, Hart protocol, Profibus/Fieldbus or with direct access to the sensor. They are appropriate for use in Group IIC and Categories 2G/D explosion-proof atmospheres. The sensor element can be installed in Category 2 explosion-proof areas in accordance with Certification 2G Ex d. The mechanical connecting element to the process can be installed in Category 2 explosion-proof areas, conform to Certification 2G Ex d. Devices labelled “Ex d” which have a mechanical separating element, such as a thermowell, are approved for Zone 0/20 to Zone 1/21, when using a sensor certified as 2GD. The temperature class and/or the surface temperature relates solely to a device operated at ambient temperature. On installation the actual temperature class for process operation has to be determined. The inlet bushings used must conform to the certification for their type in accordance with the directive.

The requirements of Regulation 94/9/CE, and the applicable national regulations for the use of measuring instruments in explosion-proof areas, such as EN 60079-0:2011, EN 60079-1:2004, EN 61241-0:2006, EN 61241-1:2004 and other regulations relating to this certification type, must be fulfilled. Only qualified specialist personnel may install devices in explosion-proof areas.

TWL

page 6 DT0454

7.3 General • When installing the sensor it is necessary to follow all the instructions and

regulations for explosion-proof areas and the safety instructions included in these instructions.

• Make sure that the details on the sensor’s type label correspond to the working conditions for the application.

• When installing the device, make sure you do not create any mechanical deformation as a result of solder spots or the application of mechanical force.

• Important: Make sure there is an electrical connection between the device’s earth and the earth of the system.

• Make sure the lid are closed before putting the device into operation.

• Before re-opening the lid, remove the plug from the mains or de-energise the device and make sure there is no danger of explosion.

• Only use cable glands according norms for Ex d protection.

• Important: Due to the use of a flame path and its fit tolerance it is not

permissible to use standard measuring inserts as spare parts 7.4 Protection against E.S.D. (Electro Static Discharge) Temperature sensors with plastic parts that can become electrically charged bear a warning label. Electrical charging must be avoided at all costs. Pay attention to the following: - Avoid rubbing the device - Never clean the device dry - Do not install the device near material airflows or near steam outlets 6.5 Maintenance and repairs The instrument does not require maintenance or servicing. Repairs must be only carried out by Kobold Mesura ( manufacturer ) 7.5 Storage Measuring instruments should be protected against humidity and dust. Storage temperature: -40ºC….+85ºC for sensors without transmitter. Storage temperature: See manual of the corresponding transmitter and display model.
